I can delete a user from a site collection, but I can't seem to delete a user totally from SharePoint.
Let's say DOMAIN\joetest has a user ID of 15. I can delete that account from the site collection (via web gui or powershell), but the next time that account is ensured the ID is still 15.
Is there a way to totally delete a user from SharePoint? So, the next time the account is ensured it has a new ID (say 150 instead of 15).
Is that even possible.
